Wiring the LCD 16?2 Keypad Shield on Arduino In this illustration we will going to wire the 16X2 LCD Keypad Shield build for Arduino UNO, MEGA, Leonardo, this board has 4 bit Arduino LCD Library. The keypad shield has select left, up, down and right push button apart from the reset button, the screen contrast adjustment is done by a 10k trimpot potentiometer at the top left corner.
- Keypad is a library for using matrix style keypads with the Arduino. As of version 3.0 it now supports mulitple keypresses. As of version 3.0 it now supports mulitple keypresses. This library is based upon the Keypad Tutorial .
- Components Needed. Arduino; 4?4 Matrix Keypad; 8 male to male pin header; The 4?4 matrix keypad can be obtained from a number of retailers online. It can be purchased at amazon and many other online retailers if you google the part.
- Connect keypad leads to 9,8,7,6 ,5,4,3,2 of arduino Digital IO pins (Right Most pin to Arduino D I/O 2 and so on) In this case, the variable key1 returns the value equivalent to the key pressed. this variable can be used to sent the values to VB interface (which will be explained in next article)
- One after another the keypad gets contacted to the arduino, until the contact from the keypad, with the number 7 on it, is connected to pin 8 on the arduino. Setup: To run the keypad with the arduino we need a library, which has to be added to the arduino software.
